Aiming at the fracture failure of flexible linkage rod which appeared usually in dual horse head pumping unite,the paper presented the example of dual horse head pumping unite which the rear horse head outline shape was Archimedes spiral,from the perspective of parame-ters of rear horse head outline shape the fracture mechanism was analyzed.According to the con-clusions and based on the obtained improvement,the dual horse head pumping unite was put for-ward.The analysis results of the improvement showed that the fracture failure of flexible linkage rod can be avoided.The conclusion in this paper has been used in the design of dual horse head pumping unite and the production practice,the application effect is very good.
